    Saw a notice on my door when I came home from class today about a "signal leakage" from Comcast. It says they discovered that their signal is "emanating out of [my] home" and that I need to make an appointment to have it fixed, or else risk them shutting down my service. Tested my internet speed to see what was up and it was down to 439 kbps...definitely NOT the high speed I'm paying for.

    So anyone know whats up with this "leakage"? How is that even possible?

    Or better yet, has anyone experienced this with Comcast before? What did you have to do to fix it?

    Been on hold now for almost an hour waiting for a technician and have somewhere to be soon. So if there's some way around this I'd really like to know!!

    Thanks.

    If you're getting that low of a bandwidth, I suspect that there's some bad cabling somewhere along the main trunk. Or possibly a bad node in your neighborhood and your neighbors are experiencing the same.

    Kinda weird that they would threaten to shut down your service.

    I assume you got through to tech support by now.
    They should facilitate the repairs providing you the proper speed and apologize for the rough treatment. See if they will extend you a free month's service. Likely a tech looked though the outside of your structure while on a unrelated service call and thought they will have to get inside. ComCast requires someone to be there when they visit.

    this should not be a big issue. I personally think its something on the out side of your house but if not have comCast come by and look through your setup inside. If they want to fix it without a charge fine. Save money; you mend the issue your self or get a geek lesbian friend (not me) to repair things. FYI: the mother of snow storms comes in this week end. Maybe its a landlord issue.

    the comCast stuff is higher end frequency so go through what you can see and affirm both the center conductor and the outer shield have a solid mechanical connection to all your devices.

    If you have two or more devices (for example tv & wifi router) you should divide the signal up using a splitter. Buy one at radio shack along with crimps and connectors.

    More likely, some of your Comcast equipment is broadcasting RF interference and needs to be replaced. They'll probably pop in another set of boxes for you and leave.

    Your equipment may be broadcasting static over WiFi channels, may be interfering with am/fm/tv signals, child monitors, garage door openers, etc. etc.

    Whenever I hear someone complaining about shitty cable, phone, or isp service it's invariably Comcast so it doesn't suprise me that they'd be heavy handed.

    Thanks guys,

    Had a tech come look at it today (after almost 2 hours on the phone yesterday). Turns out there was a loose connection that was picking up radio waves. Just a few tightened junctions and it was an easy fix! It was a pain in the ass to get it set up but the guy was knowledgeable and got the job done quickly.

    I still don't think they're a great company but at least they've got some good employees.

    They do these "audits" for several reasons. The upstream data channel sits around 27 MHZ on cable systems. That's problematic in design because it's exactly where the CB band sits, and if the cable plant is "loose" it reeks all sorts of havoc in the upstream link.

    The other reason they check for leaking RF (radio frequency) is that folks steal cable. Whod'a a thunk, right? Typically, those folks are complete and total dumb asses about the nature of RF and everyone in the systems suffers.

    When they "sniffed" your premise, they knew something was wrong, but, weren't sure what. They knew you were a paying customer, but, didn't know that maybe your neighbor wasn't, etc.

    This is a huge challenge for the cable company, because as speeds go higher RFI (Radio Frequency Interference) becomes a bigger and bigger issues.

    With better systems, like FIOS, this isn't generally an issue.

    The system has to be sniffed regularly on high speed cable data networks. Any leaks at all in the system, leakng RF, allowing RFI, bad grounds, RF induction, or moisture, can hose up whole neighborhoods, or more.
